Description

PROCEDE DE FABRICATION D'UNE EAU RICHE EN CALCIUM ET EAU PROCESS FOR THE MANUFACTURE OF WATER RICH IN CALCIUM AND WATER
OBTENUE PAR CE PROCEDE La présente invention se rapporte à un procédé de fabrication d'une eau riche en calcium et à l'eau obtenue par ce procédé. Le calcium est l'élément minéral le plus abondant dans le corps humain, réparti à 99% dans les os. Cet élément joue un rôle dans la construction osseuse, la contraction musculaire, la transmission des signaux nerveux et les échanges ioniques à travers les membranes cellulaires. Il intervient également dans la sécrétion des hormones, des enzymes digestives et des neurotransmetteurs. Les apports journaliers recommandés (AJR) en calcium sont deOBTAINED BY THIS PROCESS The present invention relates to a process for the manufacture of water rich in calcium and to the water obtained by this process. Calcium is the most abundant mineral in the human body, 99% distributed in the bones. This element plays a role in bone building, muscle contraction, transmission of nerve signals and ion exchange through cell membranes. It is also involved in the secretion of hormones, digestive enzymes and neurotransmitters. The recommended daily allowance (RDA) for calcium is
800 mg pour les hommes et les femmes de plus de 24 ans, un apport en calcium plus important étant requis lors de la grossesse et de l'allaitement par exemple.800 mg for men and women over 24 years of age, a higher calcium intake being required during pregnancy and breastfeeding for example.
Le lait, les produits laitiers et certains légumes (notamment les brocolis, le chou frisé et le persil) sont des aliments naturellement riches en calcium. L'eau peut également constituer une source importante de calcium. En effet, contrairement aux eaux de source qui sont habituellement pauvres en calcium, certaines eaux minérales sont naturellement riches en ce minéral.Milk, dairy products and some vegetables (including broccoli, kale and parsley) are foods naturally high in calcium. Water can also be an important source of calcium. In fact, unlike spring waters which are usually poor in calcium, certain mineral waters are naturally rich in this mineral.
Toutefois, dans ces eaux plates, le calcium est principalement présent sous forme de sulfate (CaSO ), forme qui est mal assimilée au niveau de l'intestin et qui confère à l'eau un goût communément qualifié de désagréable par le consommateur.However, in these still waters, calcium is mainly present in the form of sulphate (CaSO), a form which is poorly assimilated in the intestine and which gives the water a taste commonly described as unpleasant by the consumer.
Du chlorure de calcium (CaCl ) est parfois ajouté pour enrichir les eaux de bouteilles en calcium. Bien que ce sel soit très soluble dans l'eau, il ne permet pas d'obtenir une concentration en calcium très élevée, puisque la quantité de chlorure de calcium dans les eaux de boisson est limitée à 250 mg/l par les directives européennes. En outre, à l'instar du sulfate de calcium, le chlorure de calcium confère un mauvais goût à l'eau.Calcium chloride (CaCl) is sometimes added to enrich the bottled water with calcium. Although this salt is very soluble in water, it does not allow a very high calcium concentration to be obtained, since the amount of calcium chloride in drinking water is limited to 250 mg / l by European directives. In addition, like calcium sulfate, calcium chloride imparts a bad taste to water.
Le but de la présente invention est donc de pourvoir à une eau de boisson particulièrement riche en calcium qui ne présente pas les inconvénients des eaux riches en calcium antérieurement connues, ainsi qu'à un procédé de fabrication d'une telle eau.The object of the present invention is therefore to provide drinking water which is particularly rich in calcium which does not have the drawbacks of water rich in calcium previously known, as well as a process for manufacturing such water.
L'invention a pour objet un procédé de fabrication d'une eau de boisson, caractérisé en ce qu'il comprend les étapes suivantes : a) dissolution de gaz carbonique dans une eau potable faiblement minéralisée, b) passage de l'eau carbonatée obtenue à l'étape a) dans une enceinte à l'intérieur de laquelle est confiné du carbonate de calcium sous forme solide, et c) addition, à l'eau obtenue à l'étape b), d'une solution comprenant du sulfate de calcium et/ou du chlorure de calcium.The subject of the invention is a process for the manufacture of drinking water, characterized in that it comprises the following stages: a) dissolution of carbon dioxide in a weakly mineralized drinking water, b) passage of the carbonated water obtained in step a) in an enclosure inside which is confined calcium carbonate in solid form, and c) addition, to the water obtained in step b), of a solution comprising calcium sulphate and / or calcium chloride.
On entend par « eau de boisson » une eau potable apte à la consommation humaine quotidienne, eau qui ne se trouve pas telle qu'elle dans la nature mais dont la composition en éléments minéraux est ajustée par un procédé industriel.“Drinking water” is understood to mean drinking water suitable for daily human consumption, water which is not found as it is in nature but whose composition of mineral elements is adjusted by an industrial process.
Par ailleurs, on entend par « eau carbonatée » une eau comprenant du gaz carbonique et par « eau potable faiblement minéralisée » une eau potable qui ne contient pas d'ions calcium ou qui en contient moins de 50 mg/1. Il est bien entendu que l'on pourrait également utiliser une eau qui comprend moins de 150 mg/1 d'ions calcium, ou, de façon générale, toute eau qui ne contient pas le taux désiré en ions calcium.Furthermore, the term “carbonated water” is understood to mean water comprising carbon dioxide and by “weakly mineralized drinking water” a drinking water which does not contain calcium ions or which contains less than 50 mg / l thereof. It is understood that one could also use water which comprises less than 150 mg / l of calcium ions, or, in general, any water which does not contain the desired level of calcium ions.
Dans un mode de mise en œuvre avantageux du procédé conforme à l'invention, le gaz carbonique est dissous dans l'eau faiblement minéralisée, lors de l'étape a) du procédé, à un débit compris entre 4 et 10 kg/h, de manière à ce que l'eau comprenne, à l'issue de l'étape a), entre 200 et 500 mg/1 de gaz carbonique, de préférence environ 350 mg/1. Le débit de dissolution du gaz carbonique mentionné ci-dessus (de même, tous les débits qui seront indiqués dans ce qui suit) est exprimé pour un débit d'eau, au cours du procédé de fabrication d'une eau de boisson selon l'invention, de 20 m h. Un telle valeur est choisie de façon arbitraire, étant bien entendu qu'un débit d'eau différent pourrait être utilisé, par exemple dans une gamme de 80 à 200 m3/h, auquel cas les autres débits mentionnés dans ce qui suit seront ajustés en conséquence.In an advantageous embodiment of the process according to the invention, the carbon dioxide is dissolved in the weakly mineralized water, during step a) of the process, at a flow rate of between 4 and 10 kg / h, so that the water comprises, at the end of step a), between 200 and 500 mg / 1 of carbon dioxide, preferably approximately 350 mg / 1. The rate of dissolution of the carbon dioxide mentioned above (similarly, all the rates which will be indicated in the following) is expressed for a rate of water, during the process of manufacturing a drinking water according to the invention, 20 m h. Such a value is chosen arbitrarily, it being understood that a different water flow rate could be used, for example in a range of 80 to 200 m 3 / h, in which case the other flow rates mentioned in the following will be adjusted Consequently.
L'enceinte dans laquelle passe l'eau lors de l'étape b) du procédé conforme à l'invention renferme classiquement entre 150 et 500 kg de carbonate de calcium sous forme solide par m /h d'eau traitée.The enclosure through which the water passes during step b) of the process according to the invention conventionally contains between 150 and 500 kg of calcium carbonate in solid form per m / h of treated water.
L'eau obtenue à l'issue de l'étape b) comprend ainsi avantageusement entre 80 et 170 mg/1, de préférence 130 mg/1 d'ions calcium sous forme de bicarbonate. La solution utilisée lors de l'étape c) comprend par exemple entre 80 et 400 g/1, de préférence 90 g/1 de sulfate de calcium et/ou entre 100 et 300 g/1, de préférence 240 g/1 de chlorure de calcium.The water obtained at the end of step b) thus advantageously comprises between 80 and 170 mg / 1, preferably 130 mg / 1 of calcium ions in the form of bicarbonate. The solution used during step c) comprises for example between 80 and 400 g / 1, preferably 90 g / 1 of calcium sulphate and / or between 100 and 300 g / 1, preferably 240 g / 1 of chloride calcium.
Pour 20 m h d'eau traitée au cours du procédé selon l'invention, ladite solution de sulfate de calcium et ou de chlorure de calcium est avantageusement ajoutée à l'eau obtenue à l'étape b) à un débit compris entre 15 et 601/h, par exemple de 30 1/h. A l'issue de l'étape c), l'eau comprend avantageusement entre 20 et 100 mg/1, de préférence 40 mg/1 d'ions calcium sous forme de sulfate, et/ou entre 20 et 140 mg/1, de préférence 130 mg/1 d'ions calcium sous forme de chlorure.For 20 mh of water treated during the process according to the invention, said solution of calcium sulphate and or of calcium chloride is advantageously added to the water obtained in step b) at a flow rate of between 15 and 601 / h, for example 30 1 / h. At the end of step c), the water advantageously comprises between 20 and 100 mg / 1, preferably 40 mg / 1 of calcium ions in the form of sulfate, and / or between 20 and 140 mg / 1, preferably 130 mg / 1 of calcium ions in the form of chloride.
Le procédé conforme à la présente invention présente l'avantage de permettre d'obtenir une eau riche en calcium, qui comprend notamment un taux élevé d'ions calcium sous forme de bicarbonate (Ca(HCO )2). Cette forme, ionisée, présente l'avantage, par rapport aux formes sulfate et chlorure, de rendre le calcium plus disponible au niveau de l'intestin et de ne pas conférer un goût désagréable à l'eau.The process according to the present invention has the advantage of making it possible to obtain water rich in calcium, which in particular comprises a high level of calcium ions in the form of bicarbonate (Ca (HCO) 2 ). This ionized form has the advantage, compared to the sulfate and chloride forms, of making calcium more available in the intestine and of not imparting an unpleasant taste to the water.
En outre, la présence simultanée d'ions calcium sous forme de bicarbonate, de chlorure et/ou de sulfate, ainsi que la répartition entre ces différentes formes ioniques, permet d'optimiser le goût de l'eau.In addition, the simultaneous presence of calcium ions in the form of bicarbonate, chloride and / or sulfate, as well as the distribution between these different ionic forms, makes it possible to optimize the taste of water.
Le procédé décrit ci-dessus permet d'obtenir une eau plate. Si l'on souhaite obtenir une eau gazeuse, le procédé conforme à l'invention peut comprendre, après l'étape c), une étape de dissolution dans l'eau de gaz carbonique, par exemple à un débit compris entre 60 et 120 kg/h (exprimé pour un débit d'eau traitée de 20 m3/h), de façon à ce que l'eau obtenue après la dissolution du gaz carbonique comprenne entre 3 et 6 g/1 de ce gaz, de préférence environ 4,5 g/1.The process described above makes it possible to obtain still water. If it is desired to obtain carbonated water, the process according to the invention may comprise, after step c), a step of dissolving carbon dioxide in the water, for example at a flow rate of between 60 and 120 kg / h (expressed for a flow rate of treated water of 20 m 3 / h), so that the water obtained after the dissolution of carbon dioxide comprises between 3 and 6 g / 1 of this gas, preferably approximately 4 , 5 g / 1.
L'invention a également pour objet une eau de boisson, caractérisée en ce qu'elle est susceptible d'être obtenue selon le procédé tel que défini ci-dessus. Une telle eau comprend avantageusement au moins 300 mg/1 d'ions calcium.The subject of the invention is also a drinking water, characterized in that it is capable of being obtained according to the method as defined above. Such water advantageously comprises at least 300 mg / 1 of calcium ions.
L'eau selon l'invention comprend entre 80 et 170 mg/1, de préférence 130 mg/1, d'ions calcium sous forme de bicarbonate, dont les avantages sur le goût de l'eau et sur l'assimilation du calcium ont été évoqués ci-avant.The water according to the invention comprises between 80 and 170 mg / 1, preferably 130 mg / 1, of calcium ions in the form of bicarbonate, the advantages of which on the taste of water and on the assimilation of calcium have have been mentioned above.
L'eau selon l'invention peut également comprendre entre 20 et 100 mg/1, de préférence 40 mg/1, d'ions calcium sous forme de sulfate, et/ou entre 20 et 140 mg/1, de préférence 130 mg/1, d'ions calcium sous forme de chlorure.The water according to the invention can also comprise between 20 and 100 mg / 1, preferably 40 mg / 1, of calcium ions in the form of sulfate, and / or between 20 and 140 mg / 1, preferably 130 mg / 1, calcium ions in the form of chloride.
La consommation régulière de l'eau conforme à l'invention permet de couvrir une partie significative des AJR en calcium, et de réduire ainsi les risques d'une déficience en calcium, dont on connaît les conséquences néfastes sur la santé, telles que les risques d'ostéoporose et, pour les personnes âgées, de fractures osseuses.Regular consumption of water in accordance with the invention makes it possible to cover a significant part of the RDI in calcium, and thus to reduce the risks of a calcium deficiency, the harmful consequences of which are known to health, such as the risks osteoporosis and, for the elderly, bone fractures.
L'eau conforme à l'invention peut également comprendre, en outre, jusqu'à 80 mg/1, de préférence 50 mg/I, d'ions magnésium (ce qui correspond à environ 15% des AJR, qui sont de 350 mg) et/ou des agents modifiants du goût, tels que des arômes de fruits ou de menthe. De préférence, l'eau selon l'invention est une eau plate. En variante, il peut s'agir d'une eau gazeuse.The water in accordance with the invention can also further comprise up to 80 mg / l, preferably 50 mg / l, of magnesium ions (which corresponds to approximately 15% of the RDIs, which are 350 mg ) and / or taste modifiers, such as fruit or mint flavors. Preferably, the water according to the invention is still water. Alternatively, it may be sparkling water.
L'invention sera mieux comprise à l'aide de la description qui va suivre, qui se réfère à un exemple de fabrication d'une eau riche en calcium, ainsi qu'au dessin annexé, qui représente schématiquement une installation pour la mise en œuvre du procédé de fabrication selon l'invention.The invention will be better understood with the aid of the description which follows, which refers to an example of the manufacture of water rich in calcium, as well than in the accompanying drawing, which schematically represents an installation for implementing the manufacturing process according to the invention.
Il est bien entendu, toutefois, que cet exemple est donné uniquement à titre d'illustration de l'objet de l'invention, dont il ne constitue en aucune manière une limitation.It is understood, however, that this example is given only by way of illustration of the subject of the invention, of which it in no way constitutes a limitation.
La figure 1 représente une installation pour mettre en œuvre le procédé de fabrication d'une eau riche en calcium conforme à l'invention.FIG. 1 represents an installation for implementing the process for manufacturing water rich in calcium in accordance with the invention.
De l'eau brute, telle qu'une eau potable d'adduction comprenant moins de 50 mg/1 d'ions calcium, ou moins de 150 mg/1, comme évoqué précédemment, est introduite dans la canalisation 1 au moyen d'une pompe 3, à un débit compris entre 10 et 100 m3/h, par exemple égal à 20 m3/h.Raw water, such as drinking water supply comprising less than 50 mg / 1 of calcium ions, or less than 150 mg / 1, as mentioned above, is introduced into line 1 by means of a pump 3, at a flow rate between 10 and 100 m 3 / h, for example equal to 20 m 3 / h.
Du gaz carbonique, stocké dans l'enceinte 5, est dissous dans l'eau à un débit compris entre 4 et 10 kg/h, de préférence égale à 7 kg/h, de façon à obtenir une eau dont la concentration en gaz carbonique est comprise entre 200 et 500 mg/I, de préférence d'environ 350 mg/1.Carbon dioxide, stored in enclosure 5, is dissolved in water at a rate of between 4 and 10 kg / h, preferably equal to 7 kg / h, so as to obtain water with a concentration of carbon dioxide is between 200 and 500 mg / l, preferably around 350 mg / l.
L'eau chargée en gaz carbonique (« eau carbonatée ») ainsi obtenue est ensuite introduite dans une enceinte 7, par exemple de 2,5 m de hauteur et d'un diamètre cylindrique de 1,8 m, à l'intérieur de laquelle est confiné du carbonate de calcium sous forme solide. Le débit de passage de l'eau carbonatée dans l'enceinte 7 est compris entre 10 et 30 m7h, par exemple égal à 20 m3/h.The water loaded with carbon dioxide (“carbonated water”) thus obtained is then introduced into an enclosure 7, for example 2.5 m high and with a cylindrical diameter of 1.8 m, inside which is confined calcium carbonate in solid form. The flow rate of passage of carbonated water in the enclosure 7 is between 10 and 30 m7h, for example equal to 20 m 3 / h.
La réaction entre l'eau, acidifiée par la présence de gaz carbonique, et le carbonate de calcium solide aboutit à la formation de bicarbonate de calcium, sel solubilisé dans l'eau. Lors de son passage dans l'enceinte 7, l'eau se charge donc en bicarbonate et en calcium (à raison de 120 à 150 mg/1 de calcium) et s'appauvrit simultanément en gaz carbonique, dont la concentration à la sortie de l'enceinte 7 est comprise entre 150 et 250 mg/1, dans le cas présent environ 220 mg/1.The reaction between water, acidified by the presence of carbon dioxide, and solid calcium carbonate results in the formation of calcium bicarbonate, a salt dissolved in water. During its passage in enclosure 7, the water is therefore loaded with bicarbonate and calcium (at a rate of 120 to 150 mg / 1 of calcium) and simultaneously depletes in carbon dioxide, the concentration of which at the outlet of enclosure 7 is between 150 and 250 mg / 1, in the present case approximately 220 mg / 1.
Pour un débit de 20 m3 /h d'eau traitée, une solution comprenant entre 80 et 400 g/1, par exemple 90 g/1, de sulfate de calcium et/ou entre 100 et 300 g/1, par exemple 240 g/1, de chlorure de calcium, stockée dans le récipient 9, est ajoutée à l'eau enrichie en carbonate de calcium, après sa sortie de l'enceinte 7, par l'intermédiaire d'un pompe 11, à un débit d'introduction compris entre 20 et 40 1/h, par exemple égal à 30 1/h.For a flow rate of 20 m 3 / h of treated water, a solution comprising between 80 and 400 g / 1, for example 90 g / 1, of calcium sulphate and / or between 100 and 300 g / 1, for example 240 g / 1, of calcium chloride, stored in the container 9, is added to the water enriched in calcium carbonate, after it leaves the enclosure 7, by means of a pump 11, at a flow rate d introduction between 20 and 40 1 / h, for example equal to 30 1 / h.
On obtient ainsi une eau plate qui comprend, outre des ions calcium sous forme de bicarbonate, entre 20 et 100 mg/1, de préférence 40 mg/1 d'ions calcium sous forme de sulfate et/ou entre 20 et 140 mg/1, de préférence 130 mg/1 d'ions calcium sous forme de chlorure.A flat water is thus obtained which comprises, in addition to calcium ions in the form of bicarbonate, between 20 and 100 mg / 1, preferably 40 mg / 1 of calcium ions in the form of sulfate and / or between 20 and 140 mg / 1 , preferably 130 mg / 1 of calcium ions in the form of chloride.
Si l'on souhaite obtenir une eau gazeuse, du gaz carbonique, stocké dans le récipient 13, est ensuite injecté dans l'eau, a un débit compris entre 60 et 120 kg/h, de préférence égal à 90 kg/h (exprimé par rapport à un débit d'eau traitée de 20 m3/h). On obtient ainsi une eau qui comprend entre 3 et 6 g/1 de gaz carbonique, de préférence environ 4,5 g/1.If it is desired to obtain carbonated water, carbon dioxide, stored in the container 13, is then injected into the water, at a flow rate of between 60 and 120 kg / h, preferably equal to 90 kg / h (expressed in relation to a flow of treated water of 20 m 3 / h). Water is thus obtained which comprises between 3 and 6 g / l of carbon dioxide, preferably approximately 4.5 g / l.
En variante, l'obtention d'une eau gazeuse pourrait être réalisée en injectant du gaz carbonique dans l'eau en quantité suffisante en tout début de procédé. Conformément à cette variante, de 1 à 2 g/1 de gaz carbonique, issus de l'enceinte 5, sont injectés dans l'eau brute introduite dans la canalisation 1. Cette variante présente l'avantage de diminuer le dimensionnement de l'enceinte 7, qui comprend le carbonate de calcium sous forme solide : lors de l'étape b) du procédé selon l'invention, il sera possible d'utiliser 4 à 5 fois moins de carbonate de calcium par rapport à ce qui a été mentionné précédemment.Alternatively, carbonated water could be obtained by injecting carbon dioxide into the water in sufficient quantity at the very start of the process. According to this variant, from 1 to 2 g / 1 of carbon dioxide, coming from enclosure 5, are injected into the raw water introduced into the pipe 1. This variant has the advantage of reducing the dimensioning of the enclosure 7, which comprises calcium carbonate in solid form: during step b) of the process according to the invention, it will be possible to use 4 to 5 times less calcium carbonate compared to what has been mentioned previously .
L'eau obtenue, plate ou gazeuse, est enfin dirigée vers une cuve de stockage avant d'être mise en bouteille.The water obtained, still or sparkling, is finally directed to a storage tank before being bottled.
Il est bien entendu que, outre les moyens représentés schématiquement sur la figure 1, le dispositif apte à la mise en œuvre du procédé conforme à l'invention comprend d'autres moyens qui apparaîtront immédiatement nécessaires à un Homme du métier, tels que des bacs tampon, des vannes à l'entrée et à la sortie de chacun des récipients, des moyens de commande et de régulation de ces vannes, etc. It is understood that, in addition to the means shown diagrammatically in FIG. 1, the device capable of implementing the method according to the invention comprises other means which will appear immediately necessary to a person skilled in the art, such as containers. buffer, valves at the inlet and outlet of each of the receptacles, means for controlling and regulating these valves, etc.
